Abstract
PURPOSE: To efficiently separate rare earth elements by using a granular cation exchanger composed of aggregates of particles having a specified average particle size and a complexing agent.
CONSTITUTION: A developing tower provided with a jacket is packed with a granular cation exchanger composed of aggregates of particles having 30W180μm average particle size. An acceptor soln. is supplied to convert the exchanger into an acceptor type one, and by feeding an adsorbing soln. contg. a mixture of rare earth elements and a complexing agent, an adsorption zone for rare earth elements is formed. A soln. contg. a complexing agent is then fed to shift the zone by displacement development. A soln. flowing out of the lower part of the tower with the development is taken out fractionally. After the zone passes through the tower, an acceptor soln. is supplied to the tower again to allow the acceptor to be adsorbed, thereby regenerating the exchanger.
